I have the same problem at my place, and a couple client's systems, with Magnum inverter/chargers and small ~2-3kw generators (not just Honda). But the problem appliance is microwave ovens, doesn't matter which microwave brand. They run fine straight from the generator, and fine from the inverter with no generator running, but make a strange, loud hum, dim internal light, and food doesn't heat if the generator is also charging the battery bank. I'll try to figure out how to capture a waveform photo with my scopemeter and post it.
